Day 83 Brew Day Costa Cocoa Milk Stout

Brew Day 3/8/14   I think I am far enough along to breeze through the basic details. The basic brew went well, except I added 1 lb of lactose instead of 8 oz. From what I have heard, that should not be a problem. Maybe a slightly higher gravity. I started the grain steep with 3 gallons of water @ 155 for 30 minutes. I did do my little mini sparge set up. I used a bottling bucket with hose and gravity drained 2 gallons of water @ 168F over the grain sock.

Boiled for 60 minutes following directions for additions. Ice bath chilled to 125F, added 1 gallon of cold water to top-off at 5-1/2 gallons. Temp was still at 100F. So I returned the bottling bucket that I’m fermenting in, to the ice bath.

When I got it to 75F, I pulled a sample for specific gravity check and pitched the yeast (I rehydrated the Safale s-04 yeast in 4 0z of 75F water). Popped on the lid and airlock and I aerated for 5 minutes. Finished shortly after 5 pm.

I checked the OG with my new refractometer: 1.063/1.064 (those numbers are SO small!) and hydrometer: 1.060 at 80F, adjusted to 1.062…so, pretty close to each other. The original specs called for 1.053. I imagine the difference can be accounted for with the extra lactose and maybe a little better efficiency on the grain steep resulting from the mini sparge technique(?).

Update 3/9/13   9 p.m.   The wort began to ferment late last night and became pretty strong by this morning. I was away from the house for several hours and returned to find a very small amount of krausen in the airlock. It may not be necessary, but I went ahead and set up a blow off. I have 1 quart of cold brewed Kona blend coffee in the refrigerator. That will be added at bottling, after a secondary on Costa Rican chocolate nibs. This brew will eventually be “Costa Kona Mocha Latte Stout”. Did I mention that I love sitting here and writing and being able to hear the blow off chugging away in the next room? Yeah…love it. And having a glass of my homebrew Citra Citrus American Wheat doesn’t suck, either!

By the way, the strawberry blonde is continuing to clear in secondary. I’m thinking it should be ready to bottle by next weekend. The small batch of Plain Jane Blonde is in a plastic bucket, so I can’t see it; but I assume it is at least as clear as the strawberry. Maybe I’ll bottle that later this week, just to break things up a  bit. There’s about 6 gallons of strawberry, so that’s going to take awhile. The plain is only about a gallon and a half.

I hadn’t thought about it before now, but I’ll need to do some math on the corn sugar amount for bottling these blondes, since both are substantially off from the 5 gallon mark.

Day 82 Working Out Details on Costa Cocoa Milk Stout

I got this kit for my birthday. I’ve never used a couple of the ingredients in this recipe before…Costa Rican cocoa husks & cocoa nibs, and lactose (milk sugar). Sounds good, though! While doing some reading, I came across information regarding hazelnut extract…I’m thinking Nutella Stout. After mulling it over a bit, I decided to skip the trip to the brew shop for the extract because I thought it might just get to be too sweet and might not taste natural.

After some more thought…and realizing that I had a bunch of whole bean coffee on hand that I got on sale…I started looking into using coffee as an additional ingredient. Natural, not adding more sweetness, adding caffeine and making this recipe a “mocha”. Yup. That’ll do! So, I sent a message to some local brewery people for advice. They suggested making a cold brew coffee concentrate and using about an 8% by volume at bottling. I never would have thought of that! I’m actually going to go about 4 cups of concentrate, rather than 6 cups…I can always add more, but I want the chocolate to still come through.

I found a cold brew coffee recipe online from Bon Apetite  (giving credit, where due!). I adapted it to brew in a gallon carboy with an airlock, instead of some other container covered with cheesecloth. I coarsely ground 12 oz of Kona blend coffee and added it to a sanitized carboy and capped it.

Shook it up and swirled to get as much of the grounds off of the bottle as I could and then replaced the cap with a sanitized  airlock. After 15 hours at room temperature, I’ll strain out the grounds and then filter the liquid through multiple layers of cheesecloth. (If I were concerned about it being crystal clear, I would filter it through a coffee filter…slowly. I think going through a sieve and then through thick cheesecloth will be fine.) I am going to use a teaspoon of Irish moss in the boil, just to help the beer clear a little, but I’m not expecting to see through it…it IS stout, after all.

Brewing...of a different kind!

So, what I’ll be brewing will be a “Costa Kona Mocha Milk Stout”. I’m sure I’ll be sampling it as soon as I can, but I think this one might need to age until next December-ish. I think the caps that came with the kit are the “oxygen absorbing” kind…good for longer storage. Brew Day tomorrow, if I can fit it in!
